| Abstract: | The effects of growth conditions on the properties of barley starch were studied with the two‐rowed malting barley cultivars “Kustaa”; and “Kymppi”; field‐grown in Finland during a cold summer and a normal summer. In both cultivars, the growth conditions had an effect on the composition and gelatinization behaviour of both small and large granules. In the starches from the cold summer, the lipid content and gelatinization peak temperatures were lower, the gelatinized starch also being more easily hydrolysed by alpha‐amylase. |
